Amp power relay/signal wire in series?
Question:
I'm hooking up my system with two amp wiring and estra RCA's for a sub. Even though I'm only hooking up 1 amp for four component speakers. The plan is to have everything in place for a future sub and supporting amp.
My question is, do I need to somenow run a second amp power signal wire for the second amp, or can I jump it off the first amp and hook up the power signal/relay wire in series?
Thanks!

For the remote turn on you can just jump from one amp to the other, no problem.

I got a dual amp wiring kit. Comes with the proper fuses for the power and power distributer block, as well as a distributer block for the grounds. Everything seems good, except...
The only thing it seems to be missing is something for the amp "turn-on" relay wire (don't know that I'm using the correct term). I'm sure I can find a distributer block for that.
Thanks!

There's no draw on that wire, the port is just looking for the presence of 12V so you can string them together, no problem.

But I want to make sure while I have the capet tore apart for the B-Quite installation ( ) and other wire routing! Don't want to screw it up and come to find I need to tear some carpet up again when that is what I'm trying to avoid right now.

My HU has to turn on 3 amps, active crossover and eq so I ran the turn-on lead to a Bosch relay which then sent out the signal to turn everything on. Most HUs can't handle turning on more than a couple of components by itself without burning up but with the relay, you'll have the power to turn on as many as you like.

I also recommend you use a fused distribution block for your power wires and a non fused distribution block for your ground wires. Wire your car up like you plan on upgrading in the future, that way, when you do upgrade, you're already wired for it. Using distro blocks and relays mean running fewer wires through the interior too.

I don't plan on doing anything more than adding a second amp and sub in the future... but I may think about a relay for the amp switch wire.....
Thanks for the input! I appriciate it!

As long as you have your REM turn on wire run to wherever your amp is, a relay can be placed at that point and the power and ground for the relay can be tapped at the respective distro blocks you will already have there.

I have one wire connected from a switched source (accessory) in the fuse panel that runs to a Bosch relay that is wired directly to the battery. That relay sends power to my HU, my EQ, crossover and also connects to the remote turn-on Bosch relay. SO>>>>> I turn on the ingition>> I turn on the HU and the HU sends a signal to the turn-on Bosch relay which in turn tells the EQ and crossover to turn on and their power is already waiting for them since they are connected to the power relay as well. The amps also turn on from the signal from the turn-on relay and get their power from a 2 gauge wire running to a distribution block in the back.
This keeps the whole system totally isolated from my C-2's electrical system. I've never had any noise problems at all. Except from my music.

Connect terminal #87 to constant 12 volts positive with a fuse rated to the sum of the additional accessories you've added and the components you need to turn on. For example, If you have two fans rated at 5 amps each and a neon light rated at 10 amps, you would use a 20 amp fuse plus 200 ma for each amplifier and processor. Connect terminal #85 to ground, terminal #86 to the remote turn on wire from the head unit, and terminal #30 to each accessory with an appropriate fuse. A fuse (not shown) could also be used between the output of the relay (#30) and the remote turn on wire of the amplifiers and/or processors for extra precaution, but it isn't necessary.
Here is a visual diagram of a relay hookup to further illustrate my above ramblings.

Hi what value of the fuse do I need to connect on terminal 30? Is 0.5amp per amplifier? Thanks

Hi would you be able to send me the diagram how you wired amp the relay? And also what value of the fuse need to be connected on terminal 30? Is it 0.5amp per amplifier? Please be advised thank you. Here is my email add you can send the visual diagram. e2cjeffoy@gmail.com
